Quick answer
The wait for hot water is mostly the cold water sitting in the pipe between the heater and the faucet; the farther the fixture, the longer it takes, and low-flow faucets push that water out more slowly. Uninsulated pipes in cold crawl spaces make it worse. If the wait got longer suddenly, a recirculation pump, its timer, or a check valve may have failed, or a mixing valve may be stuck. Fixes include insulating hot lines, an on-demand recirculation pump, or a point-of-use heater at a distant fixture. Call (888) 217-6781 to reach a plumbing company taking calls in your ZIP.

Waiting a minute or more for hot water at a far bathroom is common. Every second you wait, cold water that was sitting in the pipe is going down the drain.
Why It Takes Time
| Cause | Why |
|---|---|
| Distance from the heater | More pipe full of cool water to push out |
| Low-flow faucets and shower heads | Push that water out more slowly |
| Large-diameter pipe | Holds more water per foot |
| Cold crawl space or slab | Pipe and water cool fast between uses |
| Tankless heater | Needs a moment to fire, and a minimum flow to start |
If It Got Worse Suddenly
- A recirculation pump near the heater, or under a far sink, may have stopped. Check that it is plugged in and its timer is set, especially after a power outage.
- A crossover or check valve in a recirc system can stick.
- A mixing valve at the heater may be stuck toward cold. See water heater not hot enough.

Fixes
- 1Insulate hot water pipes where you can reach them. The Department of Energy notes insulating pipes keeps water hotter and can let you lower the temperature setting.
- 2An on-demand recirculation pump, started by a button or motion sensor, brings hot water to the fixture before you run it.
- 3A timed recirculation system keeps hot water in the loop at busy times of day.
- 4A point-of-use water heater under a distant sink.

Frequently Asked Questions
Why does it take so long for my hot water to get hot?
Cold water in the pipe has to run out first. Long distances from the heater, low-flow fixtures and cold pipes all lengthen the wait.
How do I get hot water faster?
Insulate hot water pipes, install an on-demand or timed recirculation pump, or put a small point-of-use heater at the farthest fixture.
Why did my hot water suddenly start taking longer?
If you have a recirculation system, the pump, its timer or a check valve may have failed. Tankless heaters can also take longer if flow is below their start threshold.
